Forum d’assistance Firefox

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

My "recovery.jsonlz4" file from a previous install will not reopen my previous session (tabs) after the new installation.

Before deleting my previous installation of Firefox (for a clean install), I did two things: I created a restore point, and I did a backup of my old data.

The data consists of: bookmarks-2024-05-10.json

These folders: C:\Users\[machinename]\AppData\Local C:\Users\[machinename]\AppData\Roaming C:\Computer Files\Mozilla Firefox\distribution C:\Program Data\Mozilla-1de4eexxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Within "Roaming" I have Firefox\Profiles\xxxxxxxx.default-release\sessionstore-backups

In that sessionstore-backup, I have a "recovery.baklz4" (most recent session, I'm guessing) and three others that look like "upgrade.jsonlz4-2024xxxxxxxxxxx

With Firefox closed, I took a copy of "recovery.baklz4" (745 KB) and pasted it into the current sessionstore-backups file, then I changed the file to "recovery.jsonlz4".

I thought that when I reopened Firefox, my previous tabs would appear. They didn't. So, I went to the menu, then to History, and clicked on Recover Previous Session. That didn't do anything either. And it reduced the size of the *.jsonlz4 file from 745 KB to 6 KB.

I'm not sure what I've done wrong. Can you help me out?

Thank you.

I enter my search data or search item description into the Firefox window central to the screen, the input word and following description immediately jumps to the URL bar. How can I stop this annoying operation

When opening a new website when a window is already opened I want Mozilla to add a tab and not create an entirely new window. How do I change this feature which presumably is in "settings".

Where are all the tabs for the research I was working on? I stepped out of my office for a few minutes and returned to a very proud message declaring that Firefox had auto updated and now better than ever. Only all my tabs are gone. Why does every other browser save and restore tabs when updating, but not Firefox??? Do I have to go back to Safari or Chrome? This cannot happen!!!

I received a scam Apple (security) popup (on which I never clicked) and from that point on, some 30+ obsolete tabs congregate across the top Firefox browser window. How do i lose all these unwanted tabs?

Whenever I select tab and then start typing in the page search box it automatically jumps to the URL/Address bar. This is not only annoying but it makes it difficult for me to see what I'm typing, and it often results in unwanted typing errors. I have yet to encounter a single longtime Firefox user who thinks this is a good idea, but I have met several who've decided to drop Firefox and start using Chrome just to be done with it. I've been using Firefox since early 2005 and I've mostly been happy with it but this is just to annoying to continue. I'm complaining because the feature exits, I'm complaining because there's no option to opt for those of us who find it annoying and will never become comfortable with it.

If there is a working fix that I've been unable to find, then please point me to where or what it is so that I can apply it.

Every time I open a new tab, another extra tab opens automatically with the following address: https://0.0.0.1/

showing this message: An error occurred during a connection to 0.0.0.1.

I already re-installed Firefox but this bug keems popping up.

BTW: I did not do a d*** thing. It just started yesterday and is extremely annoying!

When searching with google it always opens a new Tab with some not working Address. Whether i just search or click on pictures or look at a picture more in detail it always opens this tab: Look at picture: At this point it is really annoying and in the settings of the browser i don't seem to find a solution. Please help.

After updating to 125.0.1 (64 bit) all my existing tabs were wiped out. Restoring the tabs does not solve the problem. Every time I close Firefox the tabs disappear.

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

I am on a brand-new machine and having trouble setting up the Firefox browser.

When I click on a link it opens in a new window with all the tabs ready opened.

How do I open a tab without opening a new window?

Also, how do I set Yahoo.com as my default search engine?

Thank you for sharing your wisdom

Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

This is the procedure I followed:

Close firefox

Copy previous.jsonlz4 file to the main level in the profile

It has all the tabs i used to have in it because I made a backup a few days ago

Rename the file to sessionstore.jsonlz4

restart firefox

I get the same single tab I had before i did this

when i go to history tabs, all that is there is the single tab i currently have

Appreciate your help/gary
